Trouble in Terrorist Town v050110

- Radio right click now sticks it on the surface you are looking at, like C4. Left click still drops it.

- Fixed radio forgetting it was yours if it was picked up and dropped with the magneto.

- Added display on the C4 model, showing the time until detonation.

-
Added client setting (ie. under F1) for ironsight crosshair opacity.
Crosshair is now no longer black while ironsighting. Those who don't
want to see it can lower opacity, while those who do want it can see it
more clearly now.

- Minor tweaks to text of teamkill highlights/"awards" to clarify the number of TKs

- Made pistol ammo show as "Pistol/M16 ammo" when picked up, because that's what it is.

- Behind the scenes: moved some NW vars to new datatable vars. Theoretically better networking performance.
